Why my screen works badly?

I connected my macbook on my television. When I disconnected the cable, my screen changed color. Since, colors are abnormal (a little bit fluorescent): I see almost nothing more. When I connect the mac on an external screen, everything works well.

I am providing you with a link to Apples troubleshooting guide for your problem. Please note the section on resetting your computer--being hooked up to the tv may have upset a setting. Since you have a good picture with an external monitor I believe your logic board is probably good.

It could be your screen but I would check the cable from the logic board to the screen first. Since I don't know exactly which Macbook you have please check number 5 (Devices) in the right column to identify your computer and then select display data cable for a guide to repair.
